MACHINE FbR MAKING PENCIL-CASES.

SPECIFICATION forming part of Letters Patent No. 515,564, dated February27, 1894.

Application filed February 24, 1893. Serial No. 463,635. (No model.)

To all whom it mag concern.-

Be it known that I, EDWARD WEIssENBoRN, a citizen of the United States,residing in J ersey City, Hudson county, New Jersey, have inventedcertain new and useful Improveever adapted to the purpose of producingva-' rious other articles similarin contour to pencil cases, and whetherhollow or solid.

In the construction of my machinel employ a hollow cylinder to receivethe plastic substance, a forming die of novel arrangement in a taperingoutlet of the cylinder, a plunger within the cylinder, for expelling thesubstance therefrom through the forming die so as to produce acontinuous molded article, and a knife, operating to out the continuousarticle into sections of equal length. I also employ a guide forreceiving the continuous molded article issuing from the forming die, soas to afford a support thereto in the action of the knife; a tray forreceiving the out sections of the molded article, and tappet-armsoperating to successively remove the sections from the tray, the wholebeing hereinafter more fully described.

In the accompanying drawings:Figure I represents a vertical longitudinalsection of a machine embodying my invention. Fig. II represents a planor top view thereof. III represents a vertical crosssection thereof onthe line os-a: of Fig. I. Fig.1V represents an inner end view of theforming die. Fig. V represents a longitudinal section thereof. Fig. VIrepresents a like section thereof at a right angle to Fig. V.

Similar letters of reference indicate similar parts.

The letter A indicates the hollow cylinder, which in practice occupies avertical position and is open at the top, while it usually has a Fig.

perforated bottom A for the purpose hereinafter explained.

B indicates the forming die, which is fitted in an outlet B in the sideof the cylinder A, near its bottom; 0 the plunger, which is fitted intothe cylinder; D the knife for cutting the molded article; a the guidetherefor; F the tray or receptacle for the cut sections of the moldedarticle, and Gthe tappet-arms for their removal from the tray.

The cylinder A, rests on a bed plate I, on which also rests an archedhood F, a portion of which constitutes the tray F. The hood Fsurmountsan opening I (Fig. I) in the bed plate; and from the hoodproject hangers J, through said opening; in which hangers are mountedtwo shafts N, O,parallelto each other, one constituting a main shaft andthe other a driving shaft. The main shaft N, carries the stock D of theknife D, in form ofa crank piece, and also carries the tappet arms G,which in this example are two in number. The driving shaft 0, is gearedwith the main shaft N, by cog wheels N, O, and it carries a graduatedspeed pulley 0 by means of which motion may be imparted thereto from anysuitable source of power.

In the hood F, are two slots G, one opposite to each of the tappet-armsG, for the passage of these arms in their motion together with the mainshaft.

The outlet B of the cylinder A, tapers in a direction outward to thecylinder, and the forming die B, corresponds exteriorly thereto, asshown, it being fitted therein from the in.- terior of the cylinder soas to retain its posi: tion without fastening, the pressure of thesubstance entering the die, from the cylinder,

tending to Wedge and tighten it in the outlet.

about the diameter of the desired case, and is mo provided with acentral core m of about the thickness of the lead or crayon to beinserted in the case, said core being held in place in the die by meansof wings s.

The plane or position of the knife D, is immediately next to the formingdie B, and between it and the guide 6, and in the action of the knife,the article cut is sustained jointly by the die and the guide. The guidec is preferably of tubular form, and it is fitted in a suitable housingP, resting on the bed plate I, for its adjustment in relation to theknife, a set screw e, retains it in the desired position. Said guide e,moreover, coincides axially with the forming die B, and its lowest pointis about on a level with the higher part of the tray F. The border ofthe tray F, is a longitudinal rib or shoulder F (Figs. II and III) atone side of the centerof the arched hood F; and if desired that portionof the hood in rear'of this rib may be omitted. The tappet arms G, arearranged to coincide with each other and to follow closely the motion ofthe knife D, as the parts revolve with the main shaft.

When the machine is to be applied to use, the desired plastic substanceis introduced into the cylinder A; and when the perforated bottom A isemployed the substance may be forced through it by means of the plunger0, placing the cylinder over an opening in the bed plate, with a view torendering the substance more homogeneous and expelling air therefrom. Inthe practical operation of the machine, however, the cylinder A, isbrought over a solid part of the bed plate I, or a solid bottom issubstituted for the perforated bottom A. Pressure being now applied tothe plunger 0, it forces and expels the plastic substance from thecylinder A, through the forming die B, producing a continuous moldedarticle of the shape of the die.

As the molded article issues from the forming die B, it is received inthe guide 6, and thence on the tray F, while at fixed intervals of timethe article is cut by means of the knife D, dividing it into sections ofequal length. vAs each cut section of the molded article clears theguide e and takes its place on the tray F, it is brought into the pathof the tappet-arms G,-

traveling in the slots G, and thereby removed from the tray, whence itmay be permitted to roll into a suitable receptacle.

What I claim as my invention, and desire to secure by Letters Patent, is

l. The hollow cylinder having an outlet with a forming die, the plungerfitted in the cylinder, the guide coinciding axially with the formingdie, and the knife lying in a plane between said die and guide,substantially as and for the purpose herein described.

2. The hollow cylinder having an outlet with a forming die, the plungerfitted in the cylinder, the guide coinciding, axially with the formingdie, the knife lying in aplanebetween said die and guide, the tray, andthe tappet arms traveling in slots of the tray, all substantially as andfor the purpose herein described.

3. The hollow cylinder having an outlet with a forming die, the plungerfitted in the cylinder, the guide coinciding axially with the formingdie, the knife lying in a plane between said die and guide, the tray,the tappet arms traveling in slots of the tray, the main shaft carryingthe stock of the knife and the tappet arms, and the driving shaft gearedwith the main shaft, all substantially as and for the purpose hereindescribed.
